Titanium Bolt Carrier Group (5.56mm / .300 BLK)
Made to exacting quality standards, our low-mass complete bolt carrier group is approximately 67% of the mass of a traditional steel full-auto profile bolt carrier group, while offering exceptional durability from the use of Grade 5 titanium coated in Ionbond DLC (Diamond Like Carbon). The bolt itself now features a nickel boron coating for ease of cleaning, better lubricity, and enhanced reliability. To truly get the most out of your titanium bolt carrier group, we recommend using this in conjunction with an adjustable gas block. This is an excellent addition for a lightweight build or for use in competition (3 gun) shooting.
Our gas keys are now staked using Forward Controls OCKS screws (Optimized Carrier Key Screw) which feature sharp, deep, effective knurling to ensure superior staking and longterm reliability.

ReviewsMark LorbieckiWhen I decided to upgrade my mil-spec bolt carrier group ("BCG"), I did a lot of research. I found a review of the Walker Defense Research BCG on Pew Pew Tactical. I was impressed by the statistics . I there and when I went to the site, found the NERO, a three-d printed muzzle device. I was impressed by the willingness to explore new technologies. I bought both a NERO and this BCG. I have a JP captured spring and a Superlative Arms adjustable gas block. With the mil-spec BCG, I could only tune the rifle to 1.5 turns into bleed (22 clicks on the detentes). It was a good result. The Walker DR BCG allowed me to bleed off another 1.5 turns (28 clicks). Because of that, I have extremely little barrel movement and keep my targets well (understand that the NERO is not on this rifle so there is no effect--this is strictly the BCG. With less mass, there is less slam. Whenever I take it to the range, others notice the smoothness and my targets. I have offhanded 120 rounds at a session and it is only my wallet that caused me to hang it up in a session. Two other things to mention: 1) my clockworks stay noticeably cleaner because I am able to bleed off so much dirty gas; and 2) the coating quality goes all the way out to the edges. This second issue needs a bit more explanation. On the mil-spec BCG the edges wore nearly immediately. The quality of the finish is so good that the edges remain crisp at 1,250 rounds. I have no reservations about recommending this BCG. I would suggest that you take full advantage by getting an adjustable gas block as well. The two together really make the gun a sweet shooter. My sons have various ARs but they always find an excuse for shooting mine.
